Book excerpt: This thesis reports on the progress made towards the design and construction of a neutral atom quantum network node using near-concentric cavities. Development of quantum network nodes is an outstanding problem towards the construction of a distributed quantum network. Fast generation of atom-atom entanglement is an important condition to make a functioning quantum node. We propose a design that uses a near-concentric cavity which is large enough to form a MOT directly inside of the cavity, while having a small enough mode volume that the photon collection efficiency is >48%: better then any free space collection method using a high-NA lens. Furthermore, the design is compact and scalable. A chip based design will limit the number of moving parts and external optics, and make the device easier to use. Future goals are to interpose a duel species array into the cavity, creating a quantum node that contains memory and processing, as well as an interface between matter qubits and photons that mediate entanglement distribution. In this work an analysis is presented showing the efficacy of the proposed platform and how it has the capability of surpassing existing entanglement generation rates using neutral atoms. Design, construction and testing of the device are ongoing. Additionally, in this thesis there is a discussion about the work done towards using neutral Rubidium 87 atoms to make Rydberg-mediated ensemble qubits. We worked to improve and fix the existing apparatus including the implementation of an automatic beam alignment system which achieved a 1[sigma] pointing stability of 60 nm between our dipole traps and the 780nm addressing beam. Multiple improvements were made to lower laser noise and stabilize experimental conditions. Problems arising in the experiment and the solutions taken to address those problems are discussed.
